[PATCH] acpi4asus update from Karol 'sziwan' Kozimor 

The attached patch updates the acpi4asus driver to 0.27 through the
following changes:
- add support for M1300A, S5200N, L8400L,
- remove WLED support for certain models, since it is not controlled by
  AML,
- add LCD backlight switching for L2E / L3H,
- C99 initializers,
- generic LED handlers,
- the output of ASYM method to provide battery state information (might be
  more accurate under certain conditions) in /proc/acpi/asus/info,
- fix several oddities, various clean-ups and other minor changes.

The patch itself is quite big, which is mostly due to the C99 initializers
and the fact that diff doesn't like moving code around.

This has been compile-tested in various configurations, the substantive
changes were discussed on the acpi4asus mailing list.

The code should apply to current bk (both for 2.4 and 2.6). The patch is
also available here:
http://hell.org.pl/~sziwan/asus/acpi4asus-0.26-0.27.diff

Thanks to all the contributors (notably Pontus Fuchs) to this release.
